You can simply bypass it by splicing the wires directly to the 4 inch subs but I do not know the wire Color codes. If one is a power wire, try to split it to both speakers. I have also considered this but mine works if I lift up the cargo lid and smack it right on the amp while a song plays at half volume. The electromagnetic relay just needs a bit of juice then mine stays on until I kill the ignition at the store lol.
